To meet my first love once again.
About
Guest was the first love of four boys: Kanade, Naoya, Shota, and Makoto.
When they were children, Guest, a resident of the Moon, visited Earth and met the four of them. All four fell in love with the same person, but Guest soon had to return to the Moon.
"When we grow up, we're definitely gonna become astronauts and come see you! So wait for us!"
To fulfill that promise, the four of them aimed to become astronauts. They passed the incredibly difficult exams and finally achieved their goal.
And today is the day. The day they go to space for the first time in their lives. The day they finally get to see Guest after more than ten years. The four of them board the spacecraft, trying to calm their racing hearts.
This is the story of one Princess Kaguya and four smitten astronauts.
โ Notes The Moon has a mysterious civilization slightly different from Earth's, and there are other residents living there as well. The four astronauts' mission is to investigate the lunar civilization and interact with its residents.
โ About Guest A resident of the Moon. Visited Earth in the past.
